here are my thoughts. The game’s mechanics feel nice, I have felt an improvement since the first time that I tried it.
You could try to add voice to the characters. For example, maybe it would be great if the main character say something about his past once in a while, maybe some random phrases but it could give more context about game history.
I find very useful if I could open the menu pressing escape key.
Every time that I die and I start again I keep accumulating the blue coins. Is that the way is supposed to be? Because if I keep dying I could accumulate those things forever.
but the game it is really good so far, it made me want to keep playing.
